Obesity appears to increase the risk of developing asthma in adulthood, reports researchers from Harvard Medical School at the American Lung Association/American Thoracic Society 1998 International Conference. After controlling for potentially confounding variables such as race, smoking and physical activity level, the investigators concluded that body mass index (a measure of obesity) has a strong, independent, positive association with risk of adult-onset asthma. There's a perfectly linear relationship. The higher the body mass index (BMI), the higher the risk of developing asthma. The researchers report that the risk for adult-onset asthma was almost three times higher in women whose BMI was 30 or more compared with women whose BMI was less than 20.
